Answer Key / Explanation : (b) -

(b)

In circuit 1,  is connected with , which is not a series combination of  junction. In circuit 2, each  junction is forward biased, hence same current flows, giving same potential difference across  junction. In circuit 2, each  junction is reverse biased, same leakage current will flow, giving equal potential difference across each  junction diode.
